Vorticity, a measure of the local rotation or swirling motion in a fluid, has long been studied by physicists and mathematicians. The dynamics of vorticity is governed by the famed Navier-Stokes equations, which tell us that ...
A trio of physicists, two with Coventry University, in the U.K., and the third with Laboratoire National des Champs Magnétiques Intenses, in France, has demonstrated how Earth's magnetic field may be influencing internal ...
Cilia are sensory structures extending from the surface of some cells. These hair-like structures are known to contribute to the sensorimotor capabilities of various living organisms, including humans.
When an object hits a body of water vertically, it is accompanied by a strong hydrodynamic force fueled by the flow of water around it, which propels it forward. The magnitude of this force is known to vary depending on the ...
The trunk of an elephant is among the versatile appendages in the animal kingdom. Now a research team has shown that most of its dexterity can be reproduced with a model using just three "muscles." And they built a physical ...
A new study in Nature Communications investigates the electrical tuning of branched light flow in nematic liquid crystal (NLC) films, revealing controlled patterns and statistical characteristics with potential applications ...
Each year at its annual meeting, the American Physical Society's Division of Fluid Dynamics sponsors a contest for the best images in a variety of categories, all related to the flow of fluids.
How much stress do pipes undergo when a liquid flows through them, and how does it depend on the degree of curvature of the pipe?
In a new study published in Physical Review Letters, scientists explore how small water jets can create stable periodic oscillations on a solid disk, uncovering a connection between these movements and the waves they generate ...
Conical structures can have advantageous applications in a variety of fields, ranging from robotics to civil engineering. Studies have found that conical shells made of liquid crystal elastomer films can be effective lifters; ...
